Calculate the density of nitrogen gas at STP, in g/L

Chemistry
1 answer:
viva [34]3 years ago
5 0

Answer:

Explanation:

To find the density of nitrogen gas at STP which is standard temperature and pressure, certain parameters must be known.

The mass of the gas must be given or its volume.

Density  of a substance is the mass per unit area;

           Volume of gas at STP  = number of moles x 22.4

Using the volume obtained here,

      Density  = \frac{mass}{volume}

Then we can find the density.

The mass is very important.

Li Ming thinks that chlorophyll is a reactant of photosynthesis, but her classmate Julian disagrees. Who is correct, and why?
Eddi Din [679]

Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis.

Explanation:

Julian is correct because chlorophyll is neither used up nor formed in the chemical reaction of photosynthesis. The reactants in photosynthesis are carbon dioxide and water.

  • Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight.
  • In photosynthesis carbon dioxide combines with water to produce glucose and oxygen.
  • Chlorophyll in plant is a green pigment that is used to trap sunlight during photosynthesis.

Pls help me. Show proof on why it’s that answer.
natulia [17]
The answer is “the sustainability of the ecosystem” because if the ecosystem isn’t sustainable enough for many different organisms to live in it then the biological diversity of the ecosystem will decrease.

A 2.0 molal sugar solution has approximately the same freezing point as 1.0 molal solution of 1) CaCl2 2) CH3COOH 3) NaCl 4) C2H
sertanlavr [38]

Answer:

3) NaCl.

Explanation:

<em>∵ ΔTf = iKf.m</em>

where, <em>i</em> is the van 't Hoff factor.

<em>Kf </em>is the molal depression freezing constant.

<em>m</em> is the molality of the solute.

<em>The van 't Hoff factor is the ratio between the actual concentration of particles produced when the substance is dissolved and the concentration of a substance as calculated from its mass. </em>

<em></em>

  • For most non-electrolytes dissolved in water, the van 't Hoff factor is essentially 1.

<em>So, for sugar: i = 1.</em>

<em>∴ ΔTf for sugar = iKf.m = (1)(Kf)(2.0 m) = 2 Kf.</em>

<em></em>

  • For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance.

For NaCl, it is electrolyte compound which dissociates to Na⁺ and Cl⁻.

<em>So, i for NaCl = 2.</em>

<em>∴ ΔTf for NaCl = iKf.m = (2)(Kf)(1.0 m) = 2 Kf.</em>

<em></em>

<em>So, the right choice is: 3) NaCl.</em>
